Tips for confused or lazy developers:
- 0:40 If you can't find the PBR Map, use the Lit Shader Graph option (Create > Shader > Universal Render Pipeline > Lit Shader Graph)
- 2:39 You can do this just by pressing space in the newer versions of URP
- "Albedo" is now "Base color"
- 3:46 If you can't find an "Alpha" Option, In your graph settings (Usually Top right corner of shader editor window) change your "Universal > Surface" from "Opaque" to "Transparent"
- 4:18 If you can't find an "Alpha clip" option you have to do the previous step but instead enable the checkbox next to "Alpha clip" (Under blend dropdown)

This shader was a life saver. Needed to fade some complex meshes in and out in URP and setting the standard lit shader to transparent caused truly horrific zwrite problems. You are a gent and scholar, much appreciated!

once again, this looks like just what I needed! thanks for the awesome work as always

[davidwollen]

This was really well explained and structured - much better than other 'tutorials' I've seen on the same subject, thankyou!

Interesting use of dither, it is essentially a dynamic texture affecting the alpha clipping level of each pixel. You can also bypass dither and make a custom script to dynamically write to a texture and avoid the dither stylization I discovered today and benefit from the alpha clipping approach in other creative ways.

Thanks a lot, the full graph at the website was very helpful.

Great easy to follow video mate, good work.

[Lukeibol]

Very nice tut, I hope you have success in your life, currently using this for a project to the company I work. Thanks

I'm not a master at this by any means. but If you find the result just being the object disappearing, I found connecting the R(1) to the multiply going to the alpha to work. 3:35

[HaniSharif]

just a quick question though, How costly is this on CPU/GPU. is this good in performance? Great video btw

[JackLaPlante]

Fantastic tutorial! I'm so glad I found your content! QQ: at 5:16 do you see how the shadow gets changed with the dithering effect? Is there any way to disable that so the shadow looks 'normal' (as it was before the effect was applied)?

[ignatiusreilly]

Thanks for the explanation, I am currently trying to get objects to fade out, and cannot manipulate the exposed Albedo from script. Let me now try it this way with dithering.

[davidwollen]

Recreated this and it works really well, with one problem - the shadows dither too. Any ideas on how to fix that?

dani just said to check out ur channel brace for veiws

[RockOn-]

Can I do this while surface type is set to opaque? I don't want to set it to transparent

[balasubramanimudaliar]

Very nice tutorial. Can we make fake transparent shader without dithering. is that possible? I try many thing but its not work. with transpernt mode its give many art fact so With opaque shader fake transparency possible?

[iDerp]

Great vid! Do you have a sense of how you'd dither an object that's occluding the player from the camera?

[Eric-pirn]

Hey, awesome tutorial! In Unity Editor it's working just fine. But exporting it to iOS causes the dithering transparency to flicker. Not the whole transparent gameobject, but the pattern of the dithering changes randomly at some random places. Any idea why that is? Thanks!

Note: I Just tried to build your example project on iOS: Same Thing ... -.-

[NocSchecter]

Hi, I am trying to edit the your shader by removing the Dither filter but I don't get the same effect that fades the transparency, can you support me or guide me what to do?

[NemesisTWarlock]

This is great, but it *really* doesn't work in VR, as the Dither node is screen-based, causing the dither pattern to move with the player's head movement. any way of getting a world based dither system?
